Application filed December 21, 1.906. Serial No. 348,928.

' Be it known that I, WnJLrAM Si TURNEY, a citizen of the United States of America, re'- sidin at Greensburg, in the county of West- 5 more and and. Stateof Pennsylvania, have invented certain new and useful Im ments in Hot-Air Furnaces, of which t e following is a specification, reference being had therein to the accompanying drawings).In

Thisinvention relates to hot-air aces especially adapted for use in dwellings; and its object is to provide a simple and inexpensive.` gas-heater for use in combination with a register to heat a building. f

The construction the 'improvement will be'ully described hereinafter in connection' with the accompanying drawingswhich form part of this s eciflcation, and its novel lfeatures will be etined in the appended claims. In the drawings, Figure 1 1s a front elevay'tion of afurnace embodying the invention.

f- Fig. 2 is a vertical section ofthe samfhig.

3 is a vertical section taken at right angles to the section-line otFig. 2; and Fig. 4 is a view in perspective, partly broken away, of one of the air-deiiecting plates employed.- The furnace is desi ed to be suspended. below the lower floor o `a building in communication with a register.

The reference-numeral 1 designates a shell or casing' preferably square in cross-section and open at top and bottom.. .A'gas-burner 2 is arrangd thelower portion of the casing, fed om a suitable sup' pl -pipe 3, and the casing is provided at sone, si ewith an opening `4, through lwhich the burner is lighted, saidV opening having va closure 5. y

Projectin from' opposite sides of the up- 4o per edge of t e casing are a suitable number of L-sha ed lugs 6 to support a conical head 7, provi ed with a square depending flange 8, adapted to rest on said lugs. The upper end oft e hood 7 tslwithin the depending rim 9 :.5 of a register 10, iitting an opening in the iioorll. s

- v'lhe furnace is suspended below the oor by wires 12 or other-'suitable suspending means, secured at their upper -ends tothe 5 o door-support 13 and at their lower ends to the lugs 6, as shown.

To opposite sides of the vcasing 1 are se-4 cured de coter-plates 14, each provided with laterally-.projecting .understood. Air entering spreader ported thereon,

flanges 15 and formed at its upper end with a hook 16, adapted to engage the upper edge of the'casing. l

The plates 14 are secured to the casing by rivets 17, extending through the iianges -15 and hooks 16, and the lower ends of said plates extend ont from the sides of the casing t0 fpm ings 19, formed in theopp'osite walls o the casing.

Within the casing 1, above the burnerfisfV secured a..hollow Vv-shaped deflector 20,

. hich serves as a spreader for the iiame iirorn` the burner.

The utility'and operation of the furnace constructed vas thus escribed will be readily through the lower open endof thecasing is heated in' its passage to the conical. dimm 7, and-the air which enters through the lower open ends of the air-chambers 18 passes into the casing" 1 through the openings'lg, adr'niXing with the air within the ,";casing above the al-shaped What I claims.. and desire to secure by Letters Patent, is--,

v1. A hot-air furnace comprising a casing openat the top and bottom and vhaving openings in its side walls, a conical hood supa gas-burner within the lower portion ofv the casing, above said burner, and deiector-plates on vopposite sides of said casing forming. air-M 2.. A hot-air furnace com rising a casing -open at top'and bottom and' aving openings in'its side walls, a conical hood supported thereon, a gas-burner `within the lower portionof the casing, a V-shaped spreader above-,said burner, and deiiector-plates secured to opposite sides of the casing to provide air-chambers, communicating with the openings formed in the side walls of the cas ing, and having laterally-extending flanges ,and hooks to securethem to the casing.

3. The combination with aregister, of a hot-air furnace suspended below-the register and comprising a casing provided at its upper end with projectin lugs and having openings'in its side we ls, a hee-:i
